A device using such a gear is disclosed in Japanese Patent Publication No. 57-33609, and the gear in this technique is mounted as shown in FIG. In FIG. 1, reference numeral 1 denotes a support column fixed to a mounting board 2, and is composed of a large diameter portion 3, a small diameter portion 4, and a retaining portion 5. Reference numeral 6 denotes a rotating body such as a gear, and a rotating shaft portion 7 rotatably attached to the large diameter portion 3 of the support 1 is formed. A first washer 8 is attached to the large diameter portion 3 of the support column 1 and is interposed between the lower end of the rotating shaft portion 7 of the rotating body 6 and the mounting board 2, and has a small coefficient of friction. Constructed from resin material. Reference numeral 9 denotes a stop washer 1 which is fitted into the small diameter portion 4 of the support column 1 and has a function of preventing the rotating body 6 from coming off.
A second washer 0 is attached to the small diameter portion 4 of the support column 1 and is interposed between the upper end of the rotating shaft portion 7 of the rotating body 6 and the stop washer 9, and is made of resin with a small friction coefficient. It is made of wood. In such a configuration, the rotation of the electric motor is transmitted to the rotating body 6, which rotates around the large diameter portion 3 of the support column 1. Such a rotating body 6 rotates around the pillar 1, but in such a configuration, the rotating body 6
Since no restricting force is applied in the axial direction, mounting play is likely to occur, and there is a problem in that such mounting play causes noise called contact noise of the rotating body.

る。(f) Effects of the invention The mounting device of the invention is capable of adjusting the axial length of the large diameter portion formed on the support to which the rotating body is attached to the axial length of the rotating shaft portion provided on the rotating body. Since the length is shorter than the sum of the thickness of the washer attached to the large diameter section, when the rotating body is attached to the column, the washer attached to the small diameter section of the column stops due to the pressure of the washer. The rotating body is deformed and the restoring force accompanying the deformation acts on the rotating body, which has the effect of reliably preventing the occurrence of mounting looseness. In addition, in the mounting device of the present invention, the washer attached to the small diameter part of the support post is deformed into the rotating shaft of the rotating body by the pressure of the stop washer, so that the axial length of the support support is shortened by the deformed length. Thus, the present invention is very effective in making tape recorders etc. thin, and its practical value is very high.
